“In the name of God, I, take you, to be my husband/wife, to have and to hold from this day forward, for better or worse, for richer or poorer, in sickness and in health, to love and to cherish all the days of my life. This is my solemn vow.”
So you still believe in fairy tale?
Time to wake up.
1 Introduction
In this project, we seek to find out features that may affect people’s marriage status. Are they truly loyal to their wedding vows? Or are there certain patterns or factors that may lead their marriage to end?
We choose ‘marital status’ and ‘number of times married’ as measurement of a person’s performance on marriage. By relating this to other factors, such as income, eduction level, or health status, we wish to find some patterns upon them.
We may find answers for some interesting questions, for example, does high income help people keep marriage steady? Should we listen to parents’ suggestions to break up with boyfriend who has a severe disease or disability? Is it a good idea to get married with a person who has a doctor degree?
Our goal is to find related factors that may bring negative effects to marriage, and avoid them.
2 Data Selection
2.1 Marriage Performance
We tag marriage performance by two measurement: ‘Marital Status’ and ‘Number of Times Married’.
fac = 1 (Good Marriage Performance): the number of times married is one and the marital status is ‘not divorced’ now, we think this person does very well in marriage.
fac = 2 (Poor Marriage Performance): the number of times married is one and the marital status is ‘divorced’ now, or the number of times is two and the marital status is ‘not divorced’ now, we think this person performs not bad in marriage.
fac = 3 (Inferior Marriage Performance): the number of times married is three, or this number is two and the marital status is ‘divorced’ now, we think this person does very poor in marriage.

4.6 Parallel Coordinates Plots
Parallel coordinates is a visualization technique used to plot individual data elements across many dimensions. Each of the dimensions corresponds to a vertical axis and each data element is displayed as a series of connected points along the dimensions/axes. This technique can have an explicit explanation of the corresponding categorical parameters.
## Parallel coordinates plots
subdata = as.data.frame(subdata)
subdata_new = subdata[,c(1,2,3,4,5,7)]
scpcp(subdata_new, sel="data[,6]", sel.palette = "w")
4.7 Interactive Parallel Coordinates Plot
Alghouth, the previous static plot shows the relationships among those categorical variabales, this interactive parallel coordinates plot presents those relationships more explicitly.
5 Conclusion
Sometimes love is blind, from the results above, we can see that income, health and education level can really influence people’s marriage. If you are not single, think more about your future and then decide whether to get married with your current couple or not. If you are single, don’t worry about your future, it is worthwhile to spend more time in looking for your soulmate.
